Products Detail

SRK1004 controller is intended for secondary side synchronous rectification (SR) in Non-Complementary Actively Clamped Flyback, Resonant Flyback, and Quasi-Resonant Flyback converters.

It provides a gate-drive output suitable for N-channel logic-level or standard level power MOSFETs.

The control scheme of this device is such that the SR MOSFET is switched on as soon as current starts flowing through its body diode and it is then switched off as current approaches zero.

The device can be supplied directly from the converter’s output voltage when operated in low-side configuration. When used in high-side configuration, it is recommended to power the IC from a dedicated auxiliary winding.

When operated in high-side configuration, a special function enables a quick detection of short-circuit conditions to inhibit its operation as if the IC were powered directly from the output voltage.

Key features

Secondary-side synchronous rectification controller optimized for Non-Complementary Actively Clamped Flyback converter (NC-ACF).
Able to operate in both low-side and high-side configuration
Supporting logic level (A, B and E) and standard level (C, D and F) MOSFETs
Two different turn-off delays available to cover a wide range of MOSFETs
Wide range supply voltage: 4 to 36 V
Very low operating current (580 µA) and quiescent current (230 µA)
High-voltage sensing input for SR MOSFET drain-source voltage (190 V AMR)
Operating frequency up to 500 kHz
Fast short-circuit detector
Tiny DFN 6L 2x2 mm package
